The chemical and optical properties of 1D single-crystalline cadmium sulfide (CdS) nanowires (NWs) synthesized by a solvothermal method were discussed systematically. CdS NW was characterized using different analytical techniques. In our work, employed as the active nanomaterial to detect ethanol gas for first time showed good sensing performance. Especially, fast response (0.4 s) recovery speed (0.2 100 ppm much faster than reported values. visible-light detector based on NWs demonstrated...
Co 3 O 4 nanofibers were prepared by an electrospinning method and characterized differential thermal gravimetric analyzer ( DTA ‐ TGA ), X‐ray diffraction XRD Fourier Transform Infrared Spectrometer FT IR scanning electron microscopy SEM ). Xylene‐sensing properties of the as‐prepared also investigated in detail. The results showed that morphology fibers was largely influenced calcination temperature. calcined at 500°C exhibited highest response to xylene a wide concentration range....

High-responsivity metal-semiconductor-metal TiO(2) UV photodetectors with Ni and Au electrodes were fabricated identically. Their Schottky barrier heights photocurrent gain mechanism studied. The effective height Φ ideality factor n evaluated according to the thermionic emission theory. result that Φ(Ni) was lower than Φ(Au) may be attributed electron transfer from substrate, which would lead a dipole layer and, accordingly, decrease height. In addition, I-V characteristics of Ni/TiO(2)/Ni...
